Subject: [PATCH 3/6] pktcdvd: remove queue_lock around blk_queue_max_hw_sectors
Date: Fri, 16 Nov 2018 09:10:03 +0100 [thread overview]
Message-ID: <20181116081006.5083-4-hch@lst.de> (raw)
In-Reply-To: <20181116081006.5083-1-hch@lst.de>
blk_queue_max_hw_sectors can't do anything with queue_lock protection
so don't hold it.
